I originally posted the advice below in a comment, but thought it could start a conversation about practical habits everyone uses to maintain self-confidence.

Like the title says, a confidence potluck where everyone brings something to the table.

Try and use a similar short form format if possible, so it’s an easy reference. Looking forward to seeing everyone’s thoughts.

What helps my inner confidence is:

When I’m in good physical shape. Doesn’t mean being ripped or overly-muscular.

Getting a good night’s sleep

Eating healthy as opposed to like crap

Engaging in a physical activity where I’m competing or working on my skills with other men. I took up kickboxing last year, and it’s humbling but pushes my comfort zone.

Taking a few minutes to close my eyes and focus on the things I have and that I’m grateful for.

Genuinely getting something accomplished with my job.

Accomplishing a personal goal or task

Doing something to make my girlfriend, friend, or family member happy without expecting anything in return.

Reading and writing

Meeting with friends

Interacting with real women and not watching pornography

On a superficial level:

Wearing clothes that fit well but are comfortable

Wearing my watch

Wearing cologne, something that makes me feel bold

Having sex
